| Total capacity: | 133ML/day |
| Date commissioned: | February 2009 |
| Feed water TDS: | 34,000 mg/L - 39,000 mg/L [1] |
| Product water TDS: | 140mg/L [2] |
| Percent of water supply: | 27% of South Eastern QLD |
| feed water temperature (low): | 17°C290.15 K 62.6 °F 522.27 °R |
| Feed water temperature (high): | 28°C301.15 K 82.4 °F 542.07 °R |
| Seawater intake system: | Submerged open sea |
| Pretreatment system: | Ferric sulphate coagulation, sulphuric acid injection (pH reduction), polyDADMAC, dual media pressure filters |
| RO operating pressure: | First pass RO operating pressure - 64 bar (45% recovery). Second pass - 15 bar (85% recovery) [3] |
| RO passes: | 2 [3] |
| RO trains: | 9, 3 |
| Post-treatment system: | Lime stabilization, CO2, disinfection by sodium hypochlorite injection |
| Concentrate disposal: | Treated supernatant discharged to sea, solids centrifuged and landfilled |
| Energy consumption: | 3.58 kWh/m3 |
| Energy recovery: | Each RO train is fitted with dual-work exchanger energy recovery devices, which recover up to 97% of unused energy from the brine. Renewable energy certificates are being used to fully offset carbon emissions from the plant. |
| Capital cost: | $1200 million |
